USPS Sets Holiday Deadlines for 2026 Delivery

For those shipping within the lower 48 states, the Postal Service suggests using USPS Ground Advantage or First-Class Mail no later than December 17. Priority Mail shipments should be processed by December 18, and Priority Mail Express users have until December 19. Deadlines for Alaska, Hawaii, Puerto Rico, and other U.S. territories are slightly tighter, with Ground Advantage shipments needing to be sent by December 16 to meet the holiday window.

Officials recommend that customers prepare early to avoid the peak rush. Detailed schedules for international and military addresses will become available on the official USPS holiday shipping portal in mid-October. The agency also provides resources for packaging guidelines and free shipping supplies through its website and dedicated YouTube channel for those managing large volumes of holiday mail.
